Ua tus LED Throwie rau 6 (rau) xees - nws yog qhov Throwie pheej yig tshaj plaws! Cov ntawv no tsis suav nrog cov hlau nplaum, txawm hais tias nws tuaj yeem ua tau.
Txoj haujlwm no siv tib lub hauv paus ntsiab lus zoo li Kev Siv Tsiaj Tus Tsiaj Lub Teeb thiab Brenn 10'sPenny thiab Nickel Battery. Nws siv cov nyiaj npib raws li cov hluav taws xob thiab cov kua txiv hmab txiv ntoo ua cov kua qaub uas koj ua rau lub roj teeb uas yuav ua rau lub zog LED. Daim vis dis aus uas qhov no yog ua raws tuaj yeem pom ntawm no. Yog tias koj nyiam cov nyiaj npib, koj yuav nyiam 500 lb. qos yaj ywm roj teeb.
Kauj ruam 1: Tau txais koj cov khoom siv
Rau qhov no koj yuav xav tau:
- 6 xus
- Ntu ntawm daim txiag ntoo los yog daim ntaub ntxeem tau
- Vinegar
- Ntsev
- LED
- Daim kab xev
- Cov ntawv xuab zeb
Kauj ruam 2: Xuab zeb Pennies
Siv cov ntawv xuab zeb lossis cov xuab zeb los tshem tawm tooj liab ntawm ib sab ntawm 5 ntawm koj cov nyiaj npib. Yog tias koj siv lub tshuab hluav taws xob thov siv lub iav kev nyab xeeb tsim nyog, thiab tsis txhob xuab zeb koj tus kheej.
Kauj Ruam 3: Sib tov Salty Acidic Solution
Kuv siv feem ntau vinegar thiab dej me ntsis, tom qab ntawd sib tov ntsev kom txog thaum nws tsis tawg.
Kauj Ruam 4: Tsau Npuag thiab Pib Sib Sau
Muab ib lub nyiaj npib nrog rau sab zinc, thiab tso ib daim ntaub ntub rau saum. Muab lwm lub nyiaj npib tig rau tib txoj kev taw qhia rau saum ntawd. Nov yog ib lub cell. Tam sim no, khaws cov khoom ua kom koj lub roj teeb muaj zog dua.
Kauj Ruam 5: Tiav Nws Tawm
Thaum koj tau kaw nws, ua tib zoo kaw nws (yog tias koj nyiam) thiab ntxig koj lub LED, nrog qhov kawg zoo rau saum. LED yuav tsum teeb. Nws tsis ci heev, tab sis rov ua dua, nws ua haujlwm tsuas yog rau xees!
